how can I, after adding multiple markers, get them and save into xml ?
thanks
I am pretty sure that it doesn't work that way. Markers know what map they belong to, but not the other way around. The way you would normally do this would be to have an Array, and each time you add a marker to your map you also add it to your array. Whenever you want to manipulate your markers you then run through that array and do the stuff that needs doing :)
What you are probably after (if you outputing stuff to XML) is just the coordinates of each marker added rather than the whole google marker object below is an example of how to get the coordinates and serialize them (badly) to XML.

The audio needs to be explicitly stopped and to do this you need the variables to be declared globally:
<script>
var audio2 = document.createElement('audio');
audio2.src = 'http://fri.ellieirons.com/wp- content/uploads/2012/03/machine.mp3' ,'' ;

I am working on a tracking system for my laptop, I used google map api to view the current location on a map...
The height % stopped working, but only for the map canvas
Why is this?
Here is the code (sorry a little messy, still sort of a noob...)
var pass_entered;
var pass_entered2;
var password="P#sSWORD";
var randomstring = Math.random().toString(36).slice(-5);
X = document.cookie.split("=")[1]
if ( X != "logged on" ) {
while (pass_entered!=password) {
pass_entered=prompt('PASSWORD REQUIRED FOR ACCESS:','');
if (pass_entered!=password){
alert("Warning! incorrect password entered");
}}}
document.cookie = "logon= logged on; path=/";
self.close();

The title says the question. Now, is it good to use a counter that starts from zero and when it is 1 or more I wouldn't add a marker. Or should I try to make it such that when someone clicks on the map the old marker disappears and the new one is assigned? The following code is what I have so far.. Thanks for any kind of help.
Also, how can I access the longitude and latitude in the next page?
And about capturing the map into a blob, is it a different topic or it is also related?
Thanks

I would say its up to you and your application later how you handle the markers.
You can implement a counter, create a dragable marker, depends how the app will work later on.
How will your next page look like?
One simple way could be something like this:
I use addListenerOnce to call the placeMarker function only one time and during this i write the latitude and longitude in a form field.
now you can add action parameters plus a submit button and you can access the values on your next page.
Thats the fiddle + code:
http://jsfiddle.net/iambnz/LcKy2/
function initialize() {
var mapOptions = {
zoom: 4,
center: new google.maps.LatLng(-25.363882,131.044922),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
google.maps.event.addListenerOnce(map, 'click', function(e) {
placeMarker(e.latLng, map);
// alert(e.latLng.toString());
document.getElementById("latitude").value = e.latLng.lat();
document.getElementById("longitude").value = e.latLng.lng();
});
}
function placeMarker(position, map) {
var marker = new google.maps.Marker({
position: position,
map: map
});
map.panTo(position);
}
google.maps.event.addDomListener(window, 'load', initialize);
I am trying to get a marker to show on the google map for a website I am doing. Without the marker code the map loads fine and shows the correct location (with no marker), when I add the marker code the map no longer loads. Clearly I am missing something simple but I am not too familiar with Jquery.

Thanks for any assistance.
The map-property is expected to be a google.maps.Map-instance and the position-property has to be a google.maps.LatLng:
Furthermore you must create the marker when the map already has been created and in a scope where the maps-instance is accessible, e.g. at the end of initialize().
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(53.154662, -1.208357),
zoom: 15,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map-canvas"),
mapOptions);
var marker = new google.maps.Marker({
position:new google.maps.LatLng(53.154662, -1.208357),
map: map,
title:"Hello World!"
});

I have published a Google Fusion table/map.
https://www.google.com/fusiontables/DataSource?docid=1bQud-ZGrJK9yBwfdasIcbU1rwJ5W9ZE53RBAeLk
My problem is that the info window does not apear when looking at the map inside html which has the map embedded. As you can see, the table is totally exposed for all users. Before I noticed this problem I had the table shared as "Everyone with the link" and thought that was the issue but no help in changing it to public.
My html with embedded map:

For the layer that is loaded at init the info window shoes up fine but not the layer that is loaded when radio button is clikced. Why?
Use a proper FusionTablesLayerOptions-object as argument for google.maps.FusionTablesLayer
layer = new google.maps.FusionTablesLayer({
query: {
select: 'Geocodable address',
from: fusionTableId
}
});
